Smart Fan with Sensor based Activation and Environment Control System

With the increasing demand for smart home-automated systems, there is a growing need for efficient and intelligent control mechanisms that enhance comfort and energy efficiency. A smart fan control system is proposed, utilizing ultrasonic and PIR sensors for reliable person detection and an LM35 temperature sensor for dynamic fan speed regulation. The system ensures immediate fan activation upon detecting a person, contributing to a comfortable environment. The LM35 sensor adjusts the fan speed based on room temperature, maximizing energy efficiency. Unlike existing approaches that rely on complex fuzzy logic systems, this method prioritizes simplicity and effectiveness. The widespread availability of sensors enhances user-friendliness without compromising functionality. The proposed system offers valuable insights into smart room control. It presents a robust solution, particularly beneficial for individuals with physical disabilities by improving their quality of life through sensor-based activation and environmental control.
